CHAPTER- I

INTRODUCTION

1.1 Brief Description of the Cluster The Cluster-XVII mines of Bharat Coking Coal Limited (BCCL), a subsidiary of

Coal India Limited (A Government of India Enterprise) is located in the

Chanch Victoria Area in Raniganj Coalfields. The coal mining activities in

Raniganj Coalfield was started during eighteenth century. The only energy

source during those years, the mining was carried out through manual and

semi-manual methods resulting into large scale degradation of land, forests

and environment. The unscientific mining resulted into large scale mine fires,

subsidence and land degradation. The mines of Raniganj Coalfield were

taken over mines by ECL and BCCL from the erstwhile private mine owners.

Most of the mines had their history from pre-nationalization period.

Mining History: There are a number of old quarries (worked before nationalization) within the

mining area of the project, apart from some UG mines near Borira village at

the dip side of the property. This project falls in West Burdwan district of West

Bengal.

Coal Block History: This coal Block was allocated to M/s West Bengal Power Development

Corporation Ltd. (WBPDCL) on 27.02.2009 and subsequently de-allocated on

21.10.2011. This block was then assigned again to Coal India Ltd along with

Brahmini and Chicro-Pastimal (Jharkhand) as per the PIB release ID : 95611

dated 06.05.2013.

There exist another coal block named Sitarampur Coal Block, situated in the

dip side of East of Damogaria (Kalyaneshwari) Block. This geologically

continuous coal block with Kalyaneshwari was allocated to M/s West Bengal


Mineral Development & Trading Corporation (WBMDTC) vide allocation

No.13016/23/2006-CA-I dated 27th December, 2007.

Both the above mentioned coal blocks were de-allocated on 25th August, 2014

vide the judgment delivered by the Honble Supreme Court of India regarding

allotment of coal blocks made by the screening committee of Govt. of India.

During the takeover of the mines in 1972 in BCCL from private mine owners,

the data like leasehold area, underground mine planning, production capacity

was unknown. However, most of the mines were further reorganized.

All the mines of BCCL were grouped into 17 clusters for preparation of

EIA/EMP report. This is because the mines are small in size and the

infrastructure is common for a number of mines.

Details of Mines in Cluster- XVII

Out of 04 old mines of pre nationalization period namely Begunia, Victoria

West Colliery, Victoria Colliery and Damagoria Colliery; the first two will

remain inoperative/non-producing and latter two, Victoria and Damagoria

leasehold are merged to form proposed Kalyaneshwari OC.

Kalyaneshwari OCP (KOCP) is proposed by the amalgamation of Victoria

Colliery and Damagoria Colliery. The area used for external OB dump will be

474.22 Ha.

Kalyaneshwari Coal Washery is also proposed in 15.66 Ha area for washing

of coal before supply to consumers.

1.2 Cluster Concept of BCCL Mines

The concept of grouping mines into a cluster arose during the meeting of

Secretary (Env.) and Secretary (Coal), GOI held on 28.02.2008 with a view

that a common EIA-EMP could be prepared for the entire cluster and

clearance obtained for all the mines in the cluster. The EAC (T&C) in the

meeting held in September 2008 discussed the matter and it was decided that

a background would be circulated to the EAC for discussion/finalization and

thereafter forwarded to the Ministry of Coal/Coal companies under M/s Coal

India Ltd to facilitate undertaking suitable study on the feasibility of cluster

approach for coal mines located in the Jharia and Raniganj coalfields.

A presentation on Feasibility study of Cluster Concept for preparation of EIA-

EMP study for cluster of mines of Bharat Coking Coal Limited was made

before the EAC (T&C) on 24.11.2009 incorporating suggestions made by the

EAC (T&C). As on 24.11.2009, the 103 mines of BCCL in Jharia and

Raniganj coalfields consisting of 65 operating mines, 34 mines closed for

production and 4 proposed mines were grouped into 17 clusters on the basis


Environmental rationale. The following environmental rationales were

considered while grouping the mines into clusters:

1. Ambient air quality in a cluster of mines.

2. Conservation of coal

3. Rock/OB waste management

4. Ecological restoration

5. Socio-economic environment

6. Fire abatement measures

7. Prominent wind direction

8. Surface hydrology

9. Environmental corridors

After discussions in details the Committee agreed with the 17 clusters

proposed and desired that the matter of clustering should ensure clear

environmental benefits and should be dovetailed with approved Master Plan,

2009(Vide letter no. J-11015/24/2009-IA.II(M), dated 2nd December, 2009).

1.3 Purpose of the report

All the mines in the Cluster started their operation prior to nationalization of

the coal mines. This Report has been prepared on the basis of Project Report

/ schemes/Feasibility Reports taking into account the present status of the

mine.


West Colliery, Victoria Colliery and Damagoria Colliery; the first two will

remain inoperative/non-producing and latter two, Victoria and Damagoria

leasehold are merged to form proposed Kalyaneshwari OC.


Colliery and Damagoria Colliery. The area used for external OB dump will be

474.22 Ha. Apart from this, it is also envisaged to design a small quarry that

may extend upto Salanpur- C seam on the eastern side of NH-2 without

diverting it.


Kalyaneshwari Coal Washery is also proposed in 15.66 Ha area for washing of

coal before supply to consumers.

The purpose of this report is to apply for grant of environmental clearance for

Cluster XVII mines of BCCL, under Cluster Concept, from Ministry of

Environment & Forests, Govt. of India in view of EIA Notification, 2006. The

Cluster will have a peak production capacity of mines 5.2 MTPA and that of

washery will be 3.60 MTPA.

1.4 Identification of Project and Project Proponent

During the takeover of the mines in 1972 in BCCL from private mine owners,

the data like leasehold area, underground mine planning, production capacity

was unknown. However, most of the mines were further reorganized. The

1.6 The importance of this Project to the country & region

Benefits at national level Bharat Coking Coal Limited is facing increasing demand of coal because of

increased demand mainly from steel industry and power sector. Continuing

and augmentation of coal production from the mines of BCCL will help to

bridge the gap of demand and supply of coal in India. Moreover BCCL is the

main producer of coking coal in the country. In order to meet the requirement

of coking coal, substantial foreign exchange has to be spent on import of

CHAPTER - II

PROJECT DESCRIPTION

2.1 BACKGROUND OF CLUSTER-XVII MINES

The Cluster-XVII mines of Bharat Coking Coal Limited (BCCL), a subsidiary of

Coal India Limited (A Government of India Enterprise) is located in the Chanch

Victoria Area in Raniganj Coalfields. The coal mining activities in Raniganj

Coalfield was started during eighteenth century. The only energy source

during those years, the mining was carried out through manual and semi-

manual methods resulting into large scale degradation of land, forests and

environment. The unscientific mining resulted into large scale mine fires,

subsidence and land degradation. The mines of Raniganj Coalfield were taken

over mines by ECL and BCCL from the erstwhile private mine owners. Most of

the mines had their history from pre-nationalization period.

Details of Normative and peak production of the cluster is given below:

coal before supply to power plant.

Cluster Concept of BCCL Mines

The concept of grouping mines into a cluster arose during the meeting of

Secretary (Env) and Secretary (Coal), GOI held on 28.02.2008 with a view that

a common EIA-EMP could be prepared for the entire cluster and clearance

obtained for all the mines in the cluster. The EAC (T&C) in the meeting held in

September 2008 discussed the matter and it was decided that a background


would be circulated to the EAC for discussion/finalization and thereafter

forwarded to the Ministry of Coal/Coal companies under M/s Coal India Ltd to

facilitate undertaking suitable study on the feasibility of cluster approach for

coal mines located in the Jharia and Raniganj coalfields.

A presentation on Feasibility study of Cluster Concept for preparation of EIA-

EMP study for cluster of mines of Bharat Coking Coal Limited was made

before the EAC (T&C) on 24.11.2009 incorporating suggestions made by the

EAC (T&C). As on 24.11.2009, the 103 mines of BCCL in Jharia and Raniganj

coalfields consisting of 65 operating mines, 34 mines closed for production

and 4 proposed mines were grouped into 17 clusters on the basis

Environmental rationale. The following environmental rationales were

considered while grouping the mines into clusters:

1. Ambient air quality in a cluster of mines.

2. Conservation of coal

3. Rock/OB waste management

4. Ecological restoration

5. Socio-economic environment

6. Fire abatement measures

7. Prominent wind direction

8. Surface hydrology

9. Environmental corridors

After discussions in details the Committee agreed with the 17 clusters

proposed and desired that the matter of clustering should ensure clear

environmental benefits and should be dovetailed with approved Master Plan,

2009(Vide letter no. J-11015/24/2009-IA.II (M), dated 2nd December, 2009).

2.2 PRESENT PROPOSAL

The purpose of this report is to apply for grant of environmental clearance for

Cluster XVII group of mines from Ministry of Environment & Forests, Govt. of

India in view of renewal of mining lease and operation of proposed

Kalyaneshwari OCP and Kalyaneshwari Coal Washery.


2.3 JUSTIFICATION FOR THE PROJECT

Bharat Coking Coal Limited is facing increasing demand of coal because of

increased demand mainly from steel industry and power sector. Continuing

and augmentation of coal production from the mines of BCCL will help to

bridge the gap of demand and supply of coal in India. To meet the growing

demand of coal, especially in power and steel sectors, BCCL has planned to

increase its production capacity. Moreover BCCL is the main producer of

coking coal in the country. In order to meet the growing demand of coking

coal, substantial foreign exchange has to be spent on import of coking coal. To

reduce the dependency, we need to enhance utilization of available resources.

2.4 GEO-MINING CHARACTERISTICS OF KALYANESHWARI OCP

PRESENT STATUS OF THE PROJECTISED AREA AND METHOD OF

MINING:

The method of mining used to extract coal and OB in Kalyaneshwari OCP is

incline slicing.

Communication and Accessibility: The Kalyaneshwari block is well

connected by road and rail. The national High-way No.2 (Grand Trunk Road)

is passing close to the southern boundary of the block and is connected by a

feeder road to the block. The by-pass (NH-2) is close to the Northern part of

the area. The Howrah-Gaya-Mugalsarai Grand-Chord passes at a distance

of about 1.5 Km. to the south of the block and Asansol-Chitranjan-Patna

Main line of Eastern Railway passes close to North-Eastern corner of the

block. The Kulti railway station on Grand Chord line is about 1 Km and is the

nearest township connected to the block by an all-weather road. The

Dhanbad and Asansol Townships are located at about 50 Km. and 15 Km.

from the block respectively.


MINE BOUNDARIES DELINEATION

Surface boundary of the proposed Kalyaneshwari OCP has been delineated

as under:

Northern Boundary: Resultant surface line drawn at about 320 from the

base of the fault F3 on the floor of Salanpur A.

Northern batter holds the most important central

haul road of the quarry.

Southern Boundary: Resultant surface line drawn at about 350 from the

floor RL of (-) 140M on the floor of Salanpur A.

Western Boundary: Resultant surface line drawn at about 370 from the

base of the fault F2 on the floor of Salanpur A.

Eastern Boundary: Minimum safety margin of 100m from NH-2 bypass.

The mine can be extended up to the limit of the East of Damagoria

(Kalyaneshwari) Block in South-Western direction under favorable

conditions, like availability of additional dumping space in the vicinity of the

mine.

Previous and present mining activity: There are a number of old quarries

(worked before nationalization) within the mining area of the project, apart

from some UG mines near Borira village at the dip side of the property. This

project falls in West Burdwan district of West Bengal.

Density of boreholes: 14 BHs/Km2 (within the project area).

Geological Structure: The geological structure of the Kalyaneshwari block is

relatively simple except for number of faults as deciphered from subsurface

data (Plate-III/Geological Plan). The strike of the strata is generally north-south

and south-west. However, in some patches, the strike swings to almost east-

west to northwest-southeast. The dip is generally towards south and south-

west and amount generally varies between 4-7; though in some cases, the

dip steep up to 10-14. Overall structure evolved from the floor contour

pattern of the coal seams indicate periclinal structure consisting of asymmetric

domes and troughs with irregular rolls.

Coal Seam: There are 16 main Barakar coal seams within the proposed

project area. Salanpur-A is the oldest seam, where as Ramnagar is the

youngest seam of the project area.

Quality of Coal Seams: Most of the coal seams of Barakar formation in this area

are considered as coking coal and its grade varies between S-II to UG.

BASE OF THE QUARRY

Floor of Salanpur A seam will form the base of the quarry for the entire strike.

ADJONING BLOCKS

On the western side of this mining block, there exists Ramnagar Block of SAIL,

which is a separate PSU falling under Ministry of Sleel & Mines, GOI. Other

block in the western side is the Victoria block of BCCL.

On the eastern side of this mining block, there exist mining blocks of ECL

namely Bonjemehary & Dalmiya of Salanpur area.

On the southern side, there exist two different mining blocks. One is Kulti

Block and the other is the Sitarampur Block.

SECTORISATION

For the purpose of estimation of mineable reserve (in mineable part of the

quarry) and overburden volume, the entire quarry has been divided into four

sectors considering the depth of the quarry (about 115m difference in depth),

which is as follows:

Sector-1: From Initial pit limit to (-) 75m FRL on Salanpur A seam.

Sector-2: From (-) 75m to (-) 110m FRL on Salanpur A seam

Sector-3: From (-) 110m to (-) 130m FRL on Salanpur A seam.


Sector-4: From (-) 130m FRL to final Pit limit on Salanpur A seam.

Sector limit on upper seams has been marked on the basis of disposition of

benches corresponding to above sector limit on Salanpur A seam and then

mineable reserve and overburden volume have been calculated through

Minex Model.

SINGLE QUARRY CONCEPT

For the purpose of viable operation, the entire project area has been

proposed to be worked in one section. This will enable further extension in

the dip side and maximizing the scope of internal dumping which in turn will

reduce the requirement of land for external dump as well as the overall lead

for OB transport.

NET GEOLOGICAL RESERVE & MINEABLE RESERVES

ACCOUNT OF RESERVES

For furnishing account of reserves, geological and mineable reserves have

been defined as follows:

Net Geological Reserve (NGR):

The reserves have been estimated upto the lower most important coal

horizon (i.e. Salanpur A seam) within delineated quarry using Minex model. It

has been calculated using Detailed resource reporting menu of MINEX

software along with separate template for each individual seam.

Mineable Reserve (MR):

A part of net geological reserve (NGR) is lost during process of exploitation.

Therefore, the part of NGR that can be exploited successfully and

transported to pit head coal stockyard is termed as mineable reserve (MR)

[Mineable Reserve = Extraction Factor x Net Geological Reserve]. Extraction

Factor is taken as 0.90.

Thus, within the proposed project area, the Net Geological Reserves (NGR)

has been assessed at 136.62MT upto Salanpur A seam (lower most coal

horizon of the property) which includes 12.34MT of Jhama. The rest

124.28MT of the reserve is coking coal.

Out of total Net Geological reserve of 136.62MT, 122.96MT is mineable as

the balance 13.66MT is estimated as mining loss during process of

exploitation.


Table 2.4: Summarized account of reserves is as follows:

1. Surface Area of the Mining Block (Sq. Km.) 3.61

2. Net Geological Reserves (MT) 136.62

3. Mineable Reserves (MT) 122.96

4. Mining Loss (MT) 13.66

GEO-MINING CHARACTERISTICS

Following geo-mining parameters have been considered for open pit design.

DIP & STRIKE

The geological structure of the Kalyaneshwari block is relatively simple

except for number of faults as deciphered from subsurface data. The strike

of the strata is generally north-south and south-west. However, in some

patches, the strike swings to almost east-west to northwest-southeast. The

dip is generally towards south and south-west and amount generally varies

between 4-7; though in some cases, the dip steep up to 10-14. Overall

structure evolved from the floor contour pattern of the coal seams indicate

periclinal structure consisting of asymmetric domes and troughs with

irregular rolls GEOLOGICAL DISTURBANCES

FAULTS

Based on the correlation of borehole data and old mine working plans, a

total of 13 numbers of faults (F1 to F13) of different magnitudes have been

deciphered within the Kalyaneshwari geological block. Out of these 13

faults, only 5(five) faults have been encountered in the proposed project

area. The detail description of these five faults which have been intersected

within project limit has been given below:

IGNEOUS ACTIVITIES

Mica Peridotite / Lamprophyre have been found to intrude the coal bearing

sedimentary strata both in the form of dykes and sills. Although dykes affect all


the seams, their effect on coal seams is found to be less as compared to that

of sills.

The effect of sills of Mica peridotite is more pronounced in terms of their extent

and effect on coal seams. Sills occur randomly and their effect on coal seams

is erratic. Effect of pyrolitization due to intrusive is most pronounced in

Salanpur-A seam. Salanpur-B seam is found to be partially affected. Upper

seams are generally free from any intrusion.

The pattern of burning of coal seams is erratic and no regular trend could be

deciphered from the borehole data. Five dykes generally trending north-west

and south-east have been located in the area. Some of these have been

encountered in the old workings. Due to extensive soil cover, the end points of

the dykes could not be marked in some cases. From the behavior of the

burning of the coal seams and occurrence of Mica Peridotite in the boreholes,

it was found that effect of sills are more pronounced and very erratic in nature.

IN-SEAM BAND (I100)

The non- combustible bands like shale, sandstone, siderite etc. irrespective of

the thickness and grey shale(ash>75%), carbonaceous shale (ash>50%) in 1

meter and above in thickness occurring within the seam, have been excluded

from the total thickness of the seam for computing the effective thickness of

coal seams for the purpose of quality consideration. Rests of the dirt bands

have been included as part of coal seam.

Bands more than 1m in thickness is specifically contained to seams Laikdih

Middle, Laikdih Bottom, Salanpur D, Salanpur C, Salanpur B, Salanpur

A. The number of inseam bands ranges from ranges from 1 to as much as 30

and the average total thickness ranges from 1m to 8m. MP, shale and

sandstone band are reported in all the above boreholes.

CHOICE OF TECHNOLOGY

Considering the mining and geological condition of the area, the shovel-

dumper combination has been proposed for mining the quarry. They are the

following:

a) Moderate dip (4o to 7o) of the coal seam.

b) Mining of multiple seams separated by multi parting.

c) Development of some of the seams in one to two sections and goaf in

patches.

d) Presence of old abandoned opencast working in some parts of the

quarry.

The opencast mining with deployment of shovel dumper combination

has been proposed. The approved opencast projects (Chaptoria OC) in

the proposed area of Kalyaneshwari OCP was proposed to be working with

shovel dumper system. Therefore the proposed system has been

continued by providing additional equipment for achieving the higher

production level.

Other technologies like Dragline, Bucket Wheel Excavator, Surface miners

are ruled out under the given geo-mining condition. The reason for not

selecting these technologies is given below.


Application of Dragline

The application of dragline is ruled out due to the following technical

reasons:

(i) The mine has moderately steep gradient unsuitable of dragline

application.

(ii) Annual workload of OB between the bottommost two coal seams does

not justify the application of dragline.

Application of Bucket Wheel Excavator

The application of Bucket Wheel is ruled out due to the following technical

reasons:

(i) The Bucket Wheel Excavator is suitable for excavating loose soil and

lignite deposits.

(ii) The mine has moderately steep gradient unsuitable of BWE application.

Application of Surface Miners

The application of Surface Miner is ruled out due to the following technical

reason:

(i) The mine has moderately steep gradient unsuitable of surface miner

application.

(ii) Surface miner can be applicable to bottom most seam i.e., Salanpur

A.

Deployment of smaller dumps truck

Smaller size dump trucks (such as 35T) have not been considered for

deployment for the following reasons:

(i) Smaller size trucks will need smaller loading shovels. The maximum

cutting height of these shovels will be lower than that of the shovels

suggested in this report. This will result in lower bench height and

increased area of excavation for the same volume of coal.

(ii) Large fleet will create problem in operation, maintenance and traffic

management.

(iii) Number of operators will increase which will adversely affect OMS

(iv) Cost per tonne cost of excavation is greater in smaller equipment

size.


EQUIPMENT SELECTION

The selection process is the most critical part of the project planning. The

selection of equipment is based on the proposed method of mining, geo-

mining characteristics of the deposit, general adopted technology in BCCL,

standardization of equipment, annual workload, equipment life and project

life.

The following selection criteria have been considered for selecting the size

and type of the equipment:

1. The strike length of the mine

2. Annual rate of advance

3. Total volume of overburden and coal to be handled annually

4. The individual thickness of coal seam and partings

5. The geo-mining condition of the mine.

6. The type of mining system to be used like Inclined Slicing or

Horizontal Slicing.

7. The intuitive economics of the mine

Based on the above selection criteria, bigger size rope shovel (10 cum)

with 100T RD is being proposed for removal of Top OB and thick parting in

horizontal slicing method. 6-8 cum Hydraulic shovel will be used to extract

the comparatively thin partings. Coal production will be carried out in

inclined slicing method by deploying 6-8 cum Hyd. Shovel with 60T RD

combination.

The proposed place of deployment (in which partings, seams, etc.) of the

selected equipment is given below.

Mining Method for Overburden Removal

Shovel-Dumper mining system has been envisaged for working this

opencast project. Bigger size Rope Shovel is envisaged for overburden

removal. Thin Partings is proposed to be mined by inclined slicing method

while the upper OB benches along with substantial partings are proposed

to be taken by horizontal slicing. There is a substantial parting between

Laikhdih Bottom and Local XI & Salanpur C and Local IX. These partings

are to be excavated using bigger shovels (10cum Rope). The working and


non-working benches have been shown in the quarry cross-sections.

These Rope Shovels are envisaged to work in conjunction with 100T Rear

Dumpers. For the estimation of the dumpers population, the lead for OB

transportation has been considered for each year and for each bench.

Mining Method for Coal Winning

Comparatively smaller size equipment has been envisaged for Coal

Winning. For coal production, 6-8 cum Hyd. Shovel with 60T RD have been

proposed in Salanpur A seam, which is the thickest of all the seams.

Other seam will also be worked with Hydraulic shovel. Some of the smaller

shovels will have backhoe attachment. One backhoe with smaller capacity

is also proposed in common to handle thin partings and dart bands. This

attachment will be useful tools in handling faulted area operation and

temporary sump formation in horizontal slicing method. For the estimation

of the dumpers population, the lead for coal transportation has been

considered for each year and for each seam. Productivity of this backhoe

has not been considered while calculation the requirement of HEMM for the

mine.

EXCAVATION

OVERBURDEN REMOVAL

The partings between the seams vary from 3m to 46m. The OB from the

benches above the coal seam is proposed to be removed by 4 nos. of

10m3 and 4 nos. of 6-8m3 electrical hydraulic shovels working in

conjunction with 100T and 60T dumpers respectively. Out of the four 6-8

m3 2 nos. of electric hydraulic shovel with backhoe attachment has been

proposed in the earliest year of the project. These backhoes will be used to

prepare the typical box-cut (batter road till the floor of the Salanpur A) of

the project. After completion of the rated life of these backhoes, they will be

replaced by same capacity front-end electric hydraulic shovel.

COAL EXTRACTION

Considering the thickness range, number of seams to be worked, status of

exploitation of seams, status of fire and production level, 2 No. of 6-8m3

Elect. Hyd. Shovel has been proposed for extraction of coal after proper

drilling and blasting. The OB shovels on upper benches will be also used

for coal extraction of upper coal seams and vice-versa.


DUMPERS

For transportation of OB 50 Nos. of 100T and 47 nos. of 60T dumpers are

proposed.

For transportation of coal 17 Nos. of 60T dumpers for working with 6-8m3

Electrical Hyd. Shovel are proposed.

DRILLS

The selection and requirement of drills has been done considering the

following:

a) Workload as per calendar plan of excavation.

b) Annual productivity of the drills.

c) Yield of mass per running meter of hole drilled.

d) Physical location of drills, within the operating sections and planned

cycle of repair and maintenance.

For drilling in OB, 12 Nos. of RBH drill of 160mm dia. has been provided.

Similarly for drilling in coal, 2 Nos. of RBH drill with 160mm dia. has been

provided.

DOZER

Considering the size and nos. of excavator in OB section, 4 nos. of 410 HP

dozer in OB with 10cum rope shovel and 4 Nos. of 410 HP dozer with 6-

8m3 rope shovel have been provided for face cleaning in coal and OB

benches. Apart from this, 2 nos. of 410HP will be fitted with ripper

attachment for preparation of coal face.

Additionally, 2 nos. of 410 HP dozer have been provided for use at OB

dump sites including reclamation.

MINING SYSTEM AND SYSTEM PARAMETERS

Considering the moderate dip (4o to 7o) of the seams, it is proposed to

excavate the OB from advance benches by inclined slicing. The variation in

thickness of OB will make it difficult to maintain uniform bench height in OB

horizons. However, it is proposed to have a ceiling on OB bench height

from safety reasons. The height of the bench generally should not exceed

the boom height of the shovel. But due to variation in thickness of parting /

cover, the bench height sometimes may exceed the boom height by few


meters temporarily for effective utilization of shovel in certain cases.

Necessary relaxation in this regard will have to be obtained from DGMS.

In the initial stage of the mine, the width of working and non-working

benches has been kept 40 and 20 m. Later on, the width of the cuts for

Shovel benches for OB will be 30 m. The maximum inclined height of the

shovel bench is proposed to be 15 m. With two way traffic along the bench,

the width of working bench of OB will be 55 m & for non-working it will be

35 m in the later years of the mine life.

The width of the cut for coal shovel varies from 10 15 m. The maximum

bench height for the coal shovel (6-8m3 Elect. Hyd. Shovel) is 10-12 m.

The width of working benches and non-working benches of coal shovels

may be kept preferably at 40 m and 25 m respectively.

The slope angle of the working benches is adopted as 70o for coal and OB

as well, while for OB dump it is adopted as 37o + 20. In the light of the

experience gained the elements of mining system can be modified during

the actual mining operations depending upon the physical and mechanical

properties of rock.

The following mining parameters have been considered in the project:
